The community as the main actor in the management of tourist attractions is very important in tourism development. The role of community can be as a medium to preserve the social cultural values in these attractions. Tanah Lot tourism attraction is one of the biggest tourist attractions in Bali which has a high number of tourist visits. Tanah Lot is managed by two parties, namely the Government of Tabanan Regency and the local community of Beraban Village. The purpose of this study was to measure the stage of community participation in the management of Tanah Lot. Community participation in the management of Tanah Lot attractions in the planning stage, the score is 2.25, the implementation stage is 4.35, the benefit-taking stage is 4.72 and the supervision stage is 4.14. The high level of community participation at the implementation, benefit-taking, supervision and evaluation stages is due to the management of Tanah Lot handed over to the Customary Village (Desa Adat). The lowest stage of community participation in management of Tanah Lot is the planning stage. The low level of community participation at this stage is due to three factors: cooperation agreement, internal factor and external factor of the community.

Cocoa is one of important commodities for the economy of Indonesia. However, national exports of the commodity has declined due to decreasing of domestic cocoa production. For enhancing cocoa production, potassium fertilization is required. Potassium (K) is an essential macronutrient in the physiology, anatomy, and yields processes. Anatomically, K is needed in the elongation of meristem tissue as well as for increasing the yields of fruit and seed. The objectives of this research included the study of the effect of K fertilizer dose and determination of optimum K doses on root anatomy development as well as the yield of cocoa pods. This research was conducted on the cocoa plantation of PT. Pagilaran. Applied doses of K fertilization consisted of 0, 150, 300, 450, and 600 g KCl/plant in Randomized Complete Block Design (RCBD) with 5 replications. Observed variables consisted of root anatomy and yield of cocoa pods. The results indicated that the dose of K fertilization significantly influenced both stele and xylem diameters of cocoa roots but insignificantly effected the thickness of cork tissue, phloem diameter, and the thickness of cambium tissue. Moreover, the dose also showed significant effect on the number of beans per pod, the weight of 100 beans, as well as the fresh and dry weight of beans per plant. It was also revealed that the dose showed no significant effect on length, diameter, and weight of the cocoa pods. It implied that K fertilization dose had effect on root anatomical properties and yield of cacao.

Sustainable livelihood is a concept achieved through strategies for utilizing livelihood assets natural, human, social, physical, and financial (DFID, 2001; Scoones, 2009; and Ellis, 2000). The Tengger tribe of Ngadas Village in Bromo Tengger Semeru National Park area (TNBTS) earns income from the agriculture and tourism sectors. Vulnerability due to natural disasters, trend changes in tourist arrivals, and climate change affect the five livelihood assets and livelihood strategies. The objective of this study is to analyze the five livelihood assets owned and to identify livelihood strategies. The descriptive qualitative method is used to assess five livelihoods by weighting and scaling. Livelihood strategies are analyzed by using interactive analysis method with primary and secondary data obtained. The results reveal that natural asset provides the highest value of financial asset, supported by social asset and physical asset. Human asset has the lowest value compared to other assets. The consolidation strategy is the dominant strategy done by dividing works between family members, hiring laborers, and using financial reserves. Other strategies are also carried out through opening a tourism business, planting new agricultural crops, maintaining the environment and culture from damaging external influences.

Development of Cultural Tourism Attractions in Ngasa Traditional Ceremonies through Community Empowerment in Kampung Budaya Jalawastu, Brebes Regency, Central Java. Upacara Adat Ngasa in Kampung Budaya Jalawastu is a cultural tourism attraction involving three community groups: the Kokolot Council, Jagabaya, and Laskar Wanoja. However, its development faces challenges in the form of low public awareness due to minimal economic impact. This study aims to determine the involvement and empowerment of the community in Upacara Adat Ngasa from psychological, political, and social aspects, as well as to analyze the development of the ceremony as a cultural tourism attraction. The methods used include interviews, observations, documentation, and questionnaires to 20 community group members. The results of the study showed an increase in self-esteem (psychological) and involvement in decision-making (political), but social empowerment was still weak due to low collaborative initiatives. In conclusion, community empowerment has been running, but social and political aspects need to be strengthened. The development of tourist attractions can be continued with optimal resource management.
